Attaching device for miner&#39;s lamp



Aug. 8, .1939. A. 'DORSEY ATTACH ING DEVICE FOR MINERS' LAMPS Filed July 15, 1938 Big INVENTOR Patented Aug. 8, 1939 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates broadly to attaching devices for miners lamps, and it has for its primary object to provide a simple and convenient form of attachment whereby a lamp may be removably mounted upon a miners cap.

A further object is to provide attachment means for a lamp associated with a miners cap whereby the lamp may be accurately guided into position in the supporting means on the cap without necessitating removal of the cap from the head of the wearer.

Another object of the invention is to provide lamp supporting means on the cap which will maintain the lamp rigidly in placeand prevent chance disengagement while in use.

Another object of the invention is to provide lamp supporting means of the character referred to designed to accommodate any of the various types of carbide or electric lamps now commonly used.

Other important objects will hereinafter be made apparent, reference being had to the accompanying drawing, in which Figure l is a perspective view of the invention, illustrating its application;

Figure 2 is a front elevational view of the capcarried lamp support;

Figure 3 is a vertical sectional view taken on line 3-3 of Fig. 2;

Figure 4 is a perspective view of a metal clip used in association with the lamp supportwhen supporting a type of lamp having a supporting hook differing from that illustrated in Figs. 1, 2 and 3; and.

Figure 5 is a side elevational view, illustrating the use of the clip shown in Fig. 4.

Referring to said drawing, the reference numeral l designates a carbide gas generating lamp having the usual reflector 2 at its front end. It will be understood, however, that, while a carbide lamp is illustrated in the drawing, the invention is adapted to be used in association with electric lamps as well.

In the embodiment illustrated in Figs. 1, 2 and 3 of the drawing, the rear of the lamp I has permanently attached thereto a strip of flat metal bent to form a tongue 3 and by means of which the lamp is designed to be supported.

The usual miners cap 4 has rigidly attached to the front portion of the top of its crown a horizontally disposed top member 5 of a stiff leather vertically extending support .6 which stands vertically in front and centrally of the crown and has its lower end suitably attached, as by rivets, to the usual visor of the cap.

Rigidlymounted, as by bolts or rivets l, to the upper end of the leather element 6 is the sheet metal lamp support plate 8. The lower end of the plate is bent upwardly to form an integral, resilient, upwardly directed hook 9 of tongue like form. Said hook 9 lies substantially parallel to the adjacent face of the plate 8 and has its upper end bent inwardly into juxtaposition to the face of the plate, a dimple l0 being preferably provided in the inwardly bent portion of the hook.

The upper edge portion of the plate 8 at opposite sides of the hook 9 is bent outwardly to form a forwardly extending and slightly upwardly inclined lip IS, the opposite lips being angularly disposed convergently toward each other, as best shown in Fig. 2 of the drawing. Extending upwardly and formed integrally with the lips I5 is a vertically disposed edge ll.

Each of the lips l5 at its inner end and in the angle between the plate 8 and lip I5 is slit to form a slot l2 into which the tongue 3 of the lamp may be inserted.

In use, the lower end of the tongue 3 of the lamp I is adapted to be inserted into the slot [2 and then depressed so that the tongue will be disposed and frictionally held intermediate the resilient hook 9 and the back plate 8, the tongue preferably having a dimple adapted toregister with the dimple IU of the hook to snap the tongue fast and retain the same against chance displacement.

It will also be noted that the rivets l are spaced apart a distance equal to the width of the lamp tongue 3 so that the rivets abut the opposite edges of the tongue and prevent lateral movement of the latter. Thus, the lamp is rigidly held in place on the cap.

Particular attention is called to the function of the lips l5. These lips serve as guides for accurately positioning the lamp in its support without necessitating removal of the cap from the head of the wearer. As is obvious, the convergently inclined lips lead to the slot l2 and the lamp tongue 3 may be placed on either of the lips and readily led or guided to the slot l2 for insertion.

Some lamps now in use are equipped with a stiff wire supporting hook 20 in lieu of the flat strip hook 3. As illustrated in Figs. 4 and 5, the present invention also provides accommodation for this form of lamp. The hook 20 is adapted to be inserted in the small aperture 22 provided in the horizontal member 5 and the lamp is thus suspended in front of the plate 8. A resilient sheet metal clip consisting of a flap central portion 23 and opposed spring fingers 25 is designed to be positioned in such a manner that the flat central portion 23 will be engaged by the hook 9 and the spring fingers 25 will project forwardly and embrace the base of the lamp and maintain the same rigid on the cap.

What is claimed is- 1. Supporting means for miners lamps, comprising in combination with a lamp having a supporting hook and a cap having a lamp supporting plate in front of the crown of said cap, a tongue formed on said plate and extending upwardly substantially parallel to the latter, convergently inclined lips formed on the upper edge of said plate, and a slot provided in said lips into which the hook of the lamp may be inserted and then depressed into frictional seating relation between the plate and the tongue.

2. Supporting means for miners lamps, comprising in combination with a lamp having a supporting hook and a cap having mounted thereon a lamp support including a vertical member and a horizontal member, a lamp supporting plate attached to the lamp support by spaced rivets, a tongue formed on said plate and extending upwardly substantially parallel to the latter, convergently inclined lips formed on the upper edge of said plate, and a slot provided in said lips in which the hook of the lamp may be inserted and then depressed into frictional seating relation between the plate and the tongue, said rivets being spaced apart a distance so as to abut the opposite vertical edges of the lamp hook when the latter is in seated relation.

3. Supporting means from miners lamps, comprising in combination with a lamp having a supporting hook and a cap having a lamp supporting plate in front of the crown of said cap, a tongue formed on said plate and extending upwardly substantially parallel to the latter, outwardly protruding lips formed on the upper edge of said plate, and a slot provided in said lips into which the hook of the lamp may be inserted and then depressed into frictional seating relation between the plate and the tongue, said tongue and said lamp hook having dimples adapted to register and frictionally engage each other when said hook is positioned in seating relation between the plate and the tongue to assist in retention of the hook.

4. In a support for miners lamps, a plate adapted to be attached to a miners cap, a tongue formed on said plate and extending upwardly substantially parallel to the latter, forwardly protruding lips formed on the upper edge of said plate, and a slot provided in said lips in vertical alignment with said tongue.
